在MySQL中从DOB查询年龄？
让我们首先创建一个表-
mysql> create table DemoTable611 (DOB date);
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable611 values('1996-04-21');
mysql> insert into DemoTable611 values('2001-01-31');
mysql> insert into DemoTable611 values('2004-12-21');
mysql> insert into DemoTable611 values('2000-02-03');使用select语句显示表中的所有记录-
mysql> select *from DemoTable611;
这将产生以下输出-
+------------+ | DOB | +------------+ | 1996-04-21 | | 2001-01-31 | | 2004-12-21 | | 2000-02-03 | +------------+ 4 rows in set (0.00 sec)
从DOB查询年龄-
mysql> select *from DemoTable611 where DOB >= (CURDATE() - INTERVAL 16 YEAR);
这将产生以下输出-
+------------+ | DOB | +------------+ | 2004-12-21 | +------------+ 1 row in set (0.00 sec)
